This invention relates to receivers for use in connection with telephones, radio sets, music instruments and the like whereby persons who are deaf can derive the same benefits therefrom as though they were not thus afflicted.

lit is an object of the invention to provide a means for engagement with a telephone receiver, music instrument or the like whereby vibrations will be transmitted to a mouthpiece tightly held between the teeth of the user, these vibrations thus being so received as to be readily distinguished and made in-' telligible to the user.

Another object is to provide a device of this character which can be positioned readily in operative relation with the element vibrated.

iVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, without departin from the spirit of the invention.

in t e accompanying drawings the preferred forms of the invention have been shown...

lln said drawings,

Figure l is a view partly in elevation and partly in section of the complete device, the same being shown connected to a telephone receiver of a radio set, telephone .or the "like.

Figure 2 is a plan view of the structure shown in higure l, a part being shown in section,

Figure 3 is a side elevation of a slightly modified form of device for use in connec tion with a musical instrument.

Referring to the figures by characters of reference 1 designates a oke having clamping screwsQ. Adjustabl y mounted in'this yolre is a threaded post 3 having a socket i in which is secured a pin 5, thlspin being held in any preferred manner as by'means of I a set screw 6 projecting into a groove 7 in the pin. A foldablerod 8 made up of pivotally connected sections is attached at one end to the pin 5 and at its other end is extended into a socket 9 formed. in the shanlr it) of a mouth-piece ll.

lln practice the yoke l is placed astride the receiver A of a radio set, telephone or the like, and is clamped thereto by means of the 1 screws 2. Post 3 is then adjusted so that one end thereof will bear upon the center of the diaphragm B of said receiver. this post can then be fastened by means of-a loch nut re. After this adjustment of the parts the mouth-piece l is gripped between the teeth of the user. When the diaphragm B .is vibrated, the vibrations will be trans mitted through the post 3 and its connections to the mouth-piece ll where they, in turn, will be detected by the nerves of the user who will thus be ableto recognize and appreciate the sound produced or transiiyitted by the vibrations of the diaphragms it modified. arrangement of this structure has been illustrated in Figure 3 for the purpose enabling the .user to appreciate sound produced by musical instruments. in this hit til

form of device the pin 13 which is connected by the rod Ill tothe mouthpiece 15 is clam ed to one member of a clutch in; This room er has a second member 17 hingedlyconnected theretoas at 18 and both of the members are provided with jaws 19. A-screw 20 is extended through the member and by tightening the same the two jaws 19 can be caused to bind on a vibrating portion of a musical instrument. Thus when the instrument is sounded the vibrations will be transmitted from the clamping element to the mouthpiece; 7

What is claimed is:

1. A device of the class described including means for clamping upon and receiving vibrations from a vibratory sound producing element, a mouth-piece, and a connection between the mouth-piece and the clamping member for conducting vibrations from said member to the mouth piece, said connection having a plurality of jointsand being swiv sled-to the clam ing member.

a A device '0 the class described including'means for clamping upon and receiving vibrations from a vibratory sound producing element, a. mouth-piece, and means for connecting the mouth-piece to said mem- 5 her for substantially universal movement relative to the clamping member, said means including a plurality of pivotally connected vibration conducting members one of which has a swivel connection with the clamping member.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.
